Logging truck standard



W` F. WEST LOGGING TRUCK STANDARD March 28, 1939.

Fiied sept. 15, 1938 @fl-T@ Patented Mar. 28, 1939 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to attachments for logging and other types of trucks designed to carry beams, logs or like material and pertains particularly to an improved form of standard.

The present invention has for its primary object to provide an improved truck standard which is designed to facilitate stacking or piling logs in such a manner that the same will be securely held in place and will not be likely to roll or slip to one side on the truck bolster to either fall off of the truck or project therefrom to such an extent as to constitute a danger and menace to other machines on the road, thereby overcoming a fault which is common with log supports or bunks of the type at present in use.

Another object of the invention is to provide an improved form of load supporting or retaining standard for logging trucks or trucks of a similar nature having transverse H-beam bolsters, wherein the standard is provided with a, base portion designed to slide in said bolster to be readily shifted toward the center or the outer end thereof whereby to accommodate the particular size of load carried, the said sliding portion of the standard further operating through its contact with the undersides of the logs as a means for maintaining the standard in vertical position at all times.

Another object of the invention is to provide a standard of the character described wherein means is provided for coupling a securing chain therewith at either of two elevations whereby the standard will be retained in adjusted position and whereby a high load may be secured, and means in the upper part of the standard facilitating the retention in connection therewith of a chain employed for rolling up logs where the same are carried over the upper ends of the standards on the chains and dropped onto the truck.

The invention will be best understood from -a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not to be confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claim.

In the drawing:

Fig. 1 is a View in side elevation of a standard constructed in accordance with the present invention, the same being shown mounted in the top channel of an H-beam bolster.

Fig. 2 is a View in top plan of the structure as shown in Fig. 1.

Fig. 3 is a View in perspective of the standard per se.

Referring now more particularly to the drawing, the numeral I generally designates a portion of a truck such as a logging truck or the like, which has extending transversely of the top thereof a number of cross-beams or bolsters of H-shape, one of which is illustrated and indicated by the numeral 2.

The beams 2 normally have at the transverse center thereof a plate or similar means 3 for attaching thereto the ends of chains 4 which eX- tend in opposite directions along the upper channel portion 5 of the beam to connect with bunks or chocks supported by the bolster adjacent the outer ends thereof. Such chocks ordinarily are of relatively low height and are designed to be engaged by only the bottom one or two logs lying across the bolster, other logs piled upon the top logs being retained in place by engaging in between the logs of the bottom row or layer. This method of stacking the logs frequently results in the logs in the upper part of the pile slipping so that one or more will be disposed obliquely of the truck and project beyond the side thereof thus endangering other cars or being likely to strike some object at the side of the truck which would cause the entire load to be shifted and possibly result in some serious damage being done.

The standard embodying the present invention is designed to overcome the foregoing difficulties and as shown in the figures of the drawing, particularly Fig. 3, it consists of a horizontal base portion or arm 6 preferably of channel iron material and a vertical right angularly disposed portion 1 of the same material secured at its lower end to one Iend of the horizontal portion 6 and rigidly braced or reinforced by the triangular side plates 8 which may be welded or otherwise suitably secured to the right angled vertical and horizontal parts. The horizontal arm 6 is of a width to lie snugly in the channel 5 of the bolster and the standard is mounted upon the bolster with the end of the horizontal arm carrying the vertical arm 'l nearest the outer end of the bolster so that the channeled portion of the ver'- tical arm will be directed toward the center of the truck.

The vertical portion 'l is provided with the upper and lower key-hole slots 9 and I0, respectively, and with a V-notch Il in the edge of the upper end.

In the use of the standard, the chain 4 at each side of the center of the bolster 2 is extended through a lower aperture of a standard supported upon the outer end of the bolster and a link of the chain is secured in the notch in the lower part of the aperture l0, as shown in Fig. 1, thus holding the standard against outward movement. From this it will be readily apparent that logs may be stacked upon the bolster 2 to rest against and be retained in place by the vertical portions 'I of the standards carried by the holsters and when they are to be removed, the chain link may be struck up into the upper part of the aperture l' in which it is located so as to permit the standard toslide outwardly and allow the logs to roll off. Itrwill also be readily seen that because of the horizontal arm portion of the standard extending inwardly under the logs, the vertical portion will be prevented from tipping outwardly as the horizontal portion will contact the bottom logs and be retained firmly in place in the channel of the bolster.

Where extra high loads' are placed upon the truck, the upper opening 9 of the vertical portion of the standard can be used to securea tie or ltoggle chain, by which is meant a chain eX- tending` across the load from a standard on one side to a standard on the opposite side. This is not necessary, however, for ordinary loads o-r loads of usual height.

The notch Il in the top edge of the Vertical portion of the standard is employed to prevent a chain extending across the upper end of the standard from slipping off when logs are rolled up on chains and loaded onto the truck by being carried in this manner over the upper ends of the standards.

From the foregoing it will be readily apparent that a standard constructed in accordance with the present invention may be easily and economically produced and will operate efficiently to maintain logs loads in place upon H-beam holsters and at the same time is so designed that it can be readily loosened when the load is leaning against the vertical portion 'I by lifting or tapping the chain upward in the aperture I0 through which it passes. Where light loads are carried, the standards may be slipped inwardly toward the center of the truck, in which case the chains passing through the lower apertures I0 would be shifted through the apertures so as to engage a link in the aperture near the inner or secured end of the chain.

What is claimed is:

A truck standard adapted to slidably position in an upwardly opening channel' of a truck bolster, comprising a base arm designed to slidably engage in said bolster channel and formed of channel material, a vertical arm of channel material secured at one end to an end o-f the horizontal arm, reinforcing web plates secured across the angle formed between said arms, said horizontal arm having the channel thereof directed upwardly and said vertical arm having the channel thereof directed inwardly toward the opposite end of. the horizontal arm, means for coupling loading chains with the vertical arm comprising a pair of vertically spaced key-hole slots formed through the vertical arm, and means for engaging a loading chain with the upper end of the vertical arm consisting of a notch formed in the upper end edge thereof.
